The VALUE COLLECTION 315080042 is a TIG torch nozzle designed to direct and shape the shielding gas flow around the tungsten electrode during TIG welding operations. This nozzle features a 6.00 mm (1/4 inch) orifice opening, corresponding to a Size 4 designation. It controls the gas coverage zone at the weld puddle, helping maintain arc stability and protect the tungsten from contamination. Welding technicians and fabricators install this nozzle as a consumable component on compatible TIG torch bodies. At 0.1 pounds, it is a lightweight, single-piece replacement part stocked individually.
This nozzle is suited for light to medium TIG welding applications where a Size 4 gas lens or standard nozzle setup is appropriate. The 6.00 mm orifice is commonly used in precision or tight-access weld joints where a smaller gas coverage envelope is preferred. It installs on torch bodies rated for this nozzle series and is appropriate for both shop and field welding environments across fabrication, pipe, and maintenance-repair-operations (MRO) contexts.
Designed for use with TIG torch bodies 17, 18, and 26 as stated by the manufacturer.
TIG torch nozzles are installed and replaced by welders or welding technicians as routine consumable maintenance. Before changing the nozzle, disconnect the torch from the power source and allow the torch body to cool completely. Thread or press the nozzle onto the torch head according to the torch body design, ensuring a snug fit to prevent shielding gas leakage. Inspect the collet body and gas lens for wear whenever replacing nozzles.
